TRAP NEST.

Application filed May 9,

1 Be it known that I, IsAAo N-VVAGGONNER, a citizen of the UnitedStates, residing at San Diego, in the county of San Diego and State ofCalifornia, have invented a certain new and useful Trap Nest,"f whichthe followingisa specification.

' My invention relates to a't'rap nest for the purpose of selectinglaying hens from a group and' the objects of my invention are: First, toprovide a nest of this class operated by the weight of the hen with atime entrance closure means so that a hen not wanting to lay may get outbefore the closure is completed; second, to provide such a means inWhichthe time of closing and opening may'be adjusted and regulated; third, toprovide a nest of this class by the use of which the hen may bepermitted to enteron one side ofa partition and exit on 'i the otherside, thus separating the hens that have laid from those that have not;fourth, to providea nest of tliisclass inwhich the entrance door isclosed and the exit door opened by the weight ofthe hen on the nest andthe exit door closed and the entrance doorbpened upon her removal fromthe nest; 'fifth, to provide suclra nest n which a partial closure ofthe exit is facilitated; sixth, to provide a novelly constructed trapnest of this class and seventh, to provide a nest of this class which ispositive in its action, adjustable, durable, efli cient and whichwillnot readily deteriorate or get out of order. v "With these and otherobjects inylew as will appear hereinafter my invention consists' ofcertain novel features of construction, combination and arrangement ofparts and portions as Will be hereinafter descrlbed in detail andparticularly set forthin the appended claims referencebeing had to theaccompanying drawings'fand' to the characters, of reference thereonwhich form a part of this application in which z Figure 1 is a frontelevation'al view of my hens nest with the entrance door open showingthe closed position of "the doors by dotted lines ;Fig. 2 is asideelevational view at a right angle from that of F ig'. 1 sho'w ing-aportion of the screen broken away to facilitate the illustration of aportion ofthe interior construction; Fig. 3 is a top or plan view of mytrap nest showing portions broken away to facilitate the. illustration;Fig. 4C is a sectional view through 4-4 of 1922. Serial no. 559,515.

Fig. 3 and showing by dotted lines'some-"of the varying operatingpositions'ofthe exit door and interior operating mechanism; Fig. 5 1s anenlarged 'deta1le'd sectionalview of the plunger and regulating valvefor*timing and regulating the closure and Fig. 6is a sim lar viewata'right angle thereto.

Similar characters of reference refer to similar parts and-portionsthroughout the several' views of the drawings.

The (using 1 116st pp n st member 3, cable 4, lever'15, lever sup t(jf'cmnk member 7, entrance door '8, Weight 9, exit door 10, weight 11,plunger rod 12, cylinder 13, plunger member 14, adjusting screw 15,

and door supports 16c0nstitute the principal parts and portions of mytrap nest.

The frame 1 is preferably hollowcube shaped but may be" other shapes ifdesired;

ltis open at thebottom and provided on the" 7 top with slats 1?. It isprovided on the front side with adoor 1 hinged area bottom andlatched'at-the' top which door 'is provided with a circular opening1"whichis the entrance opening. The-back side is also provided witha'similar hinge door'l 'w-ith an: opening in the-opposite end from theopening in the door 1 The'oppos'ite sides are provided With wiremesh,being the pre ferred construction, though they'may be ends. Theother-end of said lever Eris pivotally connected with the plunger rod12. This lever 5 is provided on its lower side with a clip member 5 aportion of which is positioned substantially parallel with the slats orsolid if desired. Pivotally mounted lever 5 and spaced some distancetherefrom.

Positioned between the lever 5 and the parallel portion, of thejmember-5 is the crank portion 7 of'the crank member 7" and this crank member isjournaled atopposite sides on the front and back sides of the frame nearthe top at the middle substantially in alignment with the support 6,Rigidly secured to'the opposite ends of this crankmember 7 are arms '7".To the "arm p 7 on the front side is secured a door meni is; closed,Reciprocably' mounted in the cylinder and pivotally connected to thelower extended end of the plunger rod 12 is a plunger member 14; whichis provided with a central hole '1 P therein. The size of said hole isregulated by means of an adjusting screw 15,'the one end of which isadapted to engage said hole for regulating the size of the opening orpassage way therethrough. This adjusting screw is mounted in threads inacross bar 1 t This cross bar is provided. with bifurcated lugs 14 whichextend 'upwardly alld between which the hollow bar- 12? is supported bymeans of a pin 12" the ends of which extend into said lugs 14.

This plunger member lt is practically the same diameter as the interiorof the cylinder 13 and. this cylinder is provided with a small quantityof oil, preferably castor oil because it is not materially affected bychange of temperature like some other oils. The oil is permitted to passthrough the opening 15 regulated by'the adjusting screw 15v forregulating the ncrement of the plunger in the cylinder 13, thusregulating the movement of the lever 5 which in turn regulates the Ymovements. of the doors the action being Par al va uum.-

' A considerable clearance is provided between the member 5 and thelever 5 for the movement of the crank portion 7? and the crank member 7therebetween thus permit-w ting a quick partial closing of the exit doorof said trap, nest While the closing of the entrance door is slow andgradual. The

lever 5 is provided with a weight 5 to raise the ne t af er h 11611 eas- It'will-be noted that: the reason for the slow closingof the entrancedoor is so that, it a. hen, happens to casually go into the nest and notfor the purpose of laying and wishes toget out again anddoes not; remainthere a y le gth of. time it can again pass out through the entrancedoor. Over the lower edge of. these doors when they are in the closedposition are provided supports 16 which are adapted to supportthe lowerside of thedoor. when, in closed position to prevent them being forcedoutwardly.

Though I have shown anddesoribed a par-.

- ticular oonsti'uction combination and arrangement of parts andportions I do. not wig-1 W be limited to this particular construction,combination and arrangement but desire to include in the scope of .myinvention the construction, combination and arrangement substantially asset forth in the appended claims.

It is obvious that with this construction there is provided a trap nestwhich may be placed in a partition between two pens so that the frontdoor opening communicates with the one pen and the other door openingwith the other of said pens; that the hen desiring to lay will passthrough the entrance opening 1, the door 8 being open as the weight ofthe nest and support are counterbalanced by the lever weight 5 andoperating mechanisms supporting the door in open position, as shown bysolid line in Fig, 1 of the drawings If the hen is simply a casualobserver and not intending to lay it may walk on the nest 01' stand onthe nest for some time, and, because of the time of slow closing of thedoor caused by the movement of the oil throughthe opening 1%, may havesufficient time to pass out through the entrance opening. However, ifthe hen remains long on the nest the entrance door will gradually closeas timed by the passage of oil through the opening 14, at the same timethe exit door will open so that after the hen has laid it will passthrough the exit door and as soon as it leaves the nest and passesthrough the door there will be a quick movement of the doors, theentrance door to open and the exit door to close for a slight distancecaused by the clearance between the portion 7 and the space between themember 5 and the lever 5 after which the entrance door as well as theexitdoor move slowly until the exit door is closedand' the entrance dooropen ready for the next hen to enter said nest; The time for opening andclosing the doors maybe regulated by the adjusting screw 15 in theplunger member 1 regulating the size of the passage 14.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. A trap nest, including a casing with an entrance opening on one sideand an exit opening on the opposite side, a nest pivotally mountedinsaid 'casing, a lever connected at one end with said nest, a plungerrod pivotally connected with the other end of said lever, a fulcrumacross said casing upon which said lever is pivotally mountedintermediate its ends; a plunger pivotally mounted on said plunger rod'and a cylinder in which said plunger is reciprocably mounted, a crankshaft mounted across said casing transversely to said lever, the crankportion of which is adapted to. engage said lever, a clip member spacedfrom said lever adapt' ed to engage the other side of said crankportion, arms secured on the opposite ends of said crank memberextending in opposite opening on the opposite side, a nest pivotallymounted in said casing, a lever connected at one end with said nest, aplunger rod pivotally connected With the other end of said lever, afulcrum across said casing upon Which said lever is pivotally mountedintermediate its ends, a plunger pivotally mounted on said plunger rodand a cylinder in Which said plunger is reciprocably mounted, a crankshaft mounted acrosssaid casing transversely to said lever, the crankportion of which is adapted to engagesaid lever, a clip member spacedfrom said lever adapted to engage the other side of said crank portion,arms secured on the opposite ends of said crank member extending inopposite directions from said crank member, doors securedto the one endsof said arms and weights secured on the opposite ends thereof,

regulating the movement of said door supporting arms. 7

3. A trap nest, including a casing, doors pivotally mounted on oppositesides of said casing, a hens nest pivotally mounted in'the bottom ofsaid casing and oil, Valve and plunger regulated means for regulatingand timing the movement of said doors operated by the pivotal movementof said nest. f

4. A trap nest, including a casing With offset openings in its front andback sides, a shaft extending across the casing, doors secured to saidshaft on opposite sides of said casing adapted to swing edgewise adaptedto cover said openings one at a timeand means actuated by the Weight ofthe hen on the nest for operating said doors.

a In testimony whereof, I have hereunto set my hand at San Diego,California, this lst day of May, 1922.
